My baby ball python Kaa has this weird scratch on his nose, right below one of heat pits. He had it when I first got him, but he wasn't/isn't on live so I don't know what else it could be from. There aren't any rough objects in his tub that he could be rubbing against.
Is is it permanent or will it go away with sheds or something?
